How to select a ntc temperature sensor?
2015-02-28

STEP 1
Your choice depends on the operating temperature range and other criteria such as:
-accuracy
-product size
-required mechanical execution i.e. naked chip, SMD, epoxy coated, surface sensor or glass sealed 
-lead length and diameter

STEP 2
Decide on the value of R25 you need .Refer to the R/T characteristic of the sensor series you chose in step 1.In these characteristic curves, each sensor in the series is distinguished by its R25-value.Choose an R25-value to give a resistance at your average temperature of operation of between 1kΩ and 100kΩ or the value that best fits your electronic measuring circuit voltage and current range.

STEP 3

Determine the tolerance on R25.

STEP 4

Using the R/T tables of the respective datasheets.

STEP 5
For other important requirements such as response time and length of component ,ect
